A conclusion to this long thread: This patch can be helpful in many situations where we need vhost lib when using vhost PMD. And driver-specific API is acceptable. And this specific function is not a candidate to be promoted in ethdev. So it should go in release 16.11. When overlooking the OVS issue related, this solution seems to be a workaround. For next release, would it be possible to find a real fix for vhost PMD and/or ethdev API instead of relying on vhost lib?
